MIL-DTL-26482 SI qualification delivers proven reliability and regulatory compliance for mission-critical assemblies. This translates to lower warranty costs and fewer field failures in aerospace, industrial automation, and defense programs. The 85100AC2236PY50 is designed for square flange receptacle integration with 1/3 bayonet mating, aligning with existing Souriau 851-series ecosystems for seamless compatibility. Cadmium plating on an aluminium shell provides robust corrosion resistance in exposed environments, extending service life and reducing maintenance cycles in outdoor equipment, control panels, and aircraft installations. The 36 solder cup contacts in a 36-position layout deliver high-density signal and power connectivity, enabling fewer connectors, simpler harnessing, and cost savings in complex systems such as avionics and robotics. The 1/3 bayonet coupling offers fast mating and secure retention, reducing maintenance time and downtime on production lines and field service. Operating from -40 to 125 °C, REACH compliant cadmium finish and a compact aluminium shell support performance across harsh thermal cycles, mitigating risk and broadening application scope in military and industrial automation. Delivered with connector support simplifies procurement and installation, enabling faster deployment, predictable lead times, and streamlined sourcing for system integrators and OEMs.

FAQs
Plan for the 53 mm length and 40x40 mm flange footprint when mounting the square flange receptacle. Ensure proper mating with the straight adaptor backshell and 1/3 bayonet coupling, and verify the Y orientation on the connector to align with the mating interface. Use cadmium finish components in exposed environments and allow for adequate clearance for serviceability during field maintenance.
Yes. The 85100AC2236PY50 is designed as part of the Souriau 851-series ecosystem, featuring a 36-position layout, 1/3 bayonet coupling, and a square flange receptacle interface. For mixed assemblies, match shell size 22, cadmium plating, and aluminium shell to maintain consistent mating tolerances and reliable performance across components.
The receptacle operates from -40 °C to 125 °C, suitable for extreme ambient conditions. It is REACH compliant and uses cadmium plating for corrosion protection, providing robust performance in harsh environments typical of aerospace, defense, and industrial automation applications.
This connector is MIL-DTL-26482 SI qualified, offering a recognized military standard for interconnect reliability. It also adheres to REACH environmental requirements and uses cadmium plating for corrosion resistance, supporting regulated use in many industrial sectors.
